ADHD: Attention Deficit Hyperactivity Disorder. BYI: Beck Youth inventories. BRIEF-A: Behavior rating of executive function. A: Adult informant form. CPT-II: Conners' continuous performance test II. FTF: Five To Fifteen. SNAP-IV: Swanson-Nolan-Pelham scale, version IV. SDQ: Strenghts and Difficulties questionnaire. WISC-IV: Wechsler intelligence scales for children, fourth version. WAIS-IV: Wechsler Adult Intelligence scales, fourth version. The number of observations varied due to partial attrition. 22 children were too young to complete the BYI at baseline.
